I'm using the proiv tree control in an app we're building. I can successfully build and display the tree, expand all, contract all, use the events and right click menu with no issues. But when I try to use some of the other methods it can't get them to work. I'm not sure if I'm just not executing them in the right place or I'm not mapping the correct parameters. Instead of the ExpandAll method, I would prefer to just expand a portion for the tree, but when I use Expand and supply the sequence number of the tree item nothing happens. I also tried using SelectItem before it, just to ensure I was on the right tree item, but still nothing. The documentation is so cryptic, and the paramentes don't seem to be consistant. For Expand it wants TreeItem, for SelectItem it want Handle. To me they should both want the same parameter. But they are both nummeric, so I've just used the same numeric scratch variable in their maps.


Has anyone used these methods sucessfully that can help?

Charlie,

We used code similar to the following

$RowData = selected key sequence of our table containing the tree
#ROWID = TreeName.FindByData(FBD) where FBD is an interface containing $RowData (see PROIV Properties doc for FindByData)
TreeName.SelectItem(EXP) where EXP is an interface containing #ROWID
TreeName.Expand(EXP)

Hope this helps.
